Methods The different activity intensities recorded by accelerometer were distinguished into a certain different energy expenditure value by gas metabolism method. Forty-one participants wore the accelerometer for 7 days continuously and completed physical activity logs everyday at the same time. The total energy expenditure was evaluated by these methods. Results Total energy expenditure evaluated by accelerometer was (9761 +/- 866) kJ/d [(2332 +/- 207) kcal/d, PAL 1.46 +/- 0.11] for male and (7526 +/- 879) kJ/d [ (1798 +/- 210) kcal/d,P AL 1.43 +/- 0.09 for female; whereas combining accelerometer and physical activity logs data showed that the total energy expenditure was (10 573 +/- 804) kJ/d [(2526 +/- 192) kcal d, PAL 1.58 +/- 0.10] for male, and 8191 +/- 737 kJ/d [(1957 +/- 176) kcal/d, PAL 1.56 +/- 0.08] for female. Conclusions Using accelerometer and physical activity logs to evaluate the total energy expenditure might be consistent with the existing data, so this method might be used to survey the individual energy expenditure and physical activity levels.Read More
